Glycemic control as the main determinant factor of serum VEGF levels in type 2 diabetes mellitus patients

Abstract

<b>Introduction.</b> Diabetes mellitus (DM) is a main endocrine disorder that may cause vascular complications as the disease progresses. Vascular endothelial growth factor (VEGF) has been linked to the development of micro and macrovascular diabetic complications. This study aimed to assess several factors including blood pressure, body mass index, lipid profile, kidney function, and glycemic control that may provide the rise of serum VEGF levels in type 2 DM subjects. <b>Methods.</b> This cross-sectional study was carried out among 65 type 2 DM subjects. Systole, diastole, mean arterial pressure (MAP), and body mass index (BMI) were measured. The levels of serum VEGF were measured by Enzyme-linked immunosorbent assay (ELISA), Hemoglobin A1c (HbA1c) levels were measured by latex agglutination inhibition test, while serum glucose, lipid profiles, urea, and creatinine levels were tested by enzymatic photometric method. <b>Results.</b> The levels of serum VEGF had a significant correlation with BMI (p = 0.001, r = 0.397), fasting plasma glucose (FPG) (p = 0.001, r = 0.418), HbA1c (p < 0.001, r = 0.600), systole (p = 0.001), r = 0.397), diastole (p = 0.021, r = 0.286), and MAP (p = 0.001, r = 0.001). Further multivariate linear regression analysis revealed that HbA1c logarithm (log) was the determinant factor of VEGF levels (p < 0.001, β = 0.631, Adjusted R² = 38.9%) <b>Conclusion.</b> HbA1c is the main determinant factor of serum VEGF levels among type 2 DM patients.
